My boys went to the Spires and as they both have some learning differences that was a mixed bag. They were great for autism but not so great for dyslexia but it was a while ago.
TA has a new building and has significantly improved.
The Cuthbert Maine Catholic school has resolved the religious issue of centuries and is a mixed Roman Catholic and Protestant and friends whose children go there rate it well.
Watcombe primary has had investment and although lots of disadvantaged children go there apparently it offers a lot of extra curriculum and cultural opportunities. Ilsham would be considered highly desirable though.
My DD used to teach at Priory. It's squeezed in with no green space so it wouldn't be top of my list. There is a wide variety of primary schools.
The town center has the same issues as all towns, particularly sea side ones but there is still good shops and the harbour is great in the summer. A family member is part of a team looking at solutions with the levelling up funds around the area and there is investment.
Personally I think it is as good as anywhere and better than many with some really lovely things to do. Walking, outdoor sports, the sea, so many beaches, the moors. Exeter is lovely to visit (Topsham is a bit like a theme park for old fashioned independent shops etc).
Clark's village is about 90 minutes away but worth going.
People holiday in Torquay so they must think it's ok. I still feel like I'm on holiday every summer and I've been local for over a decade.
